pywintypes.error : (0, 'SetCursorPos', 'No error message is available') on using Regex

[jagadeesh1983]

Hi,

I am using Python 2.7 (64 bit) with pyWinAuto 0.6.3 (64 bit) on Windows 2012 R2 (64 bit) to automate 64-bit application.
I am getting following error when we use regex for title_re.

<class 'pywintypes.error'>: (0, 'SetCursorPos', 'No error message is available')

Here is my Code snippet:

app = application.Application().connect(title_re='.*Application Designer.*')
app.window_(title_re = 'Application Designer.*').MenuSelect('File->Delete')

However, when we connect to our application by giving complete name of window through title then we are not facing above mentioned issue.

Below code works fine:

app = application.Application().connect(title='Application Designer - Untitled')
app.window_(title_re = 'Application Designer.*').MenuSelect('File->Delete')

Please let me know how to fix this issue if I need to use regex in my pywinauto code.

Thanks,
Jagadeesh

Hi @jagadeesh1983 do you run the script as Administrator? It looks like insuffient privileges issue so far.

Hi Vasily,

Yes, I have logged in to the Windows 2012 R2 machine as administrator and ran the script.

Thanks,

It might be insufficient to login as administrator (if UAC is enabled, default runtime mode could be non-privileged). Try popup menu "Run as Adminiostrator" for the script or your IDE.

Hi @jagadeesh1983 is the issue still relevant?

[bugmeout]

same problem on win7 server2012 R2. it's not stable, sometimes goes wrong.

traceback like that:

Hi Vasily,

I am not working on pyWinAuto project now. So that issue is not relevant for me.
You can close this ticket if you want.

Thanks,

I'm running into the same error when attempting to run a script on a Windows VM as part of a robotframework test, but only when running it without a Remote Desktop connection. If I'm connected to the machine when the script runs, everything works fine and I can observe the effects on the application that's being automated.

The error occurs in the function:

def gui_click_save(self):
  """Clicks File->Save in the menu."""
  m = self.main_form.Menu()
  m_file = m.GetMenuPath('File')[0].SubMenu()
  m_file_save = m_file.GetMenuPath('Save')[0]
  m_file_save.click()

Edit: in my case, enclosing self.ctrl.set_focus() at menuwrapper.py:323 in a try..catch block seems to allow the script to run as intended. Apparently, at least SetCursorPos and SetForegroundWindow fail in the case of the VM without an active Remote Desktop session.

Hi @lippinj this problem is not pywinauto related (though error message might be more meaningful), because RDP window provides GUI context for an automation. See issue #401 with more details on how to resolve it different ways.
